To apt whom itm y concern:

citizen of the United States, Tyler, the countyof Y Texas, have invented certain new and useful by 'djeclare and exact description which it appertains Joints. wnlennor TYLER, rnxAs.

' WRENCH.

G. Wnrenrfa residing at and State of Be it'known that 1, JOHN Smith This invention relates to wrenches and more particularly to that type generally known as the spanner wrench.

The invention has for its primary object to provide an improved spanner wrench inwrench head in I wrench, partly broken away,

for reliably retaining the I proper position with relation to thefobject to be rotated.

With this and other objects in view, theeluding means invention consists in the novel construction,

arrangement and formation of parts as'will be hereinafter specifically described, claimed and illustrated 1n the accompanying drawing, in which: I

. Figurel represents a fragmental perspectiv'e view of the wrench complete. Fig; 2 represents 'a side elevation of the improved wrench, partly in section, and applied to use. Fig. 3 represents a side elevation of the illustrating the same applied to use. Fig. l representsia perspective view of the holder removed. Fig. 5 represents a fragmental perspective view of the annular head and adjacent portion of the handle of the wrench. Fig. 6 repre- .sents a fragmental sectional view on the line 6-6 of Fig. 2. Fig.

mental'perspective View of the centering ele- 7 represents a fragment for the wrench removed- I Referring to the drawing in detail, wherein similar reference numerals designate cor-* responding parts throughout the several views, the numeral 5 indicates the handle or shank of the wrench, which is formed at one end with an enlarged annular head 6 formed .at one edge'with aninwardly directed annular flange 8. j The side face of the annular head 6 opposite the flange 8 is formed with a plurality of axially projecting ribs or wings 7 The end of the wrench handle 5 opposite the head 6 is formed-with a lateral enlargementor head 7. I I A holder designated generallyby the nu-' meral9 includes a body plate 10, preferably of circular formation and provided with a Specification bf Letters Patent.

Application filed May 25, 1915. Serial no. 30,349,:

radial recess 11 andfa semicircular laterally latter is proprojecting flange 12, which and adapted to cooperate therewith in.hold-' ing'the wrench head 6 inp'osition upon the object to be rotated, 'as will hereinafter appear.

Acen'tering' element 13 is providedwith a cylindrical shank' adapted to be rotatably mounted within the annular head 6 and a flange 14 adjacent that end adapted to engage the flange 8 of the head 6 to limit the outward movement of the shank 13 with relation to the head 6, in one direction. The oppositeends 15 of the shank are preferably of-polygonal formation, whereby the center- 'ing element may be used for removing washer nuts. v The wrench isespecially designed for use in removing annular or washer. nuts 16,

which are often-used for holding gage glasses 19 of sight feed oiling systems.

The glass 19. is retained in position in they holder 16 by the washer nut-18 and the holder 16 is formed at its outeredge with a plurality of spaced recesses for the re- .ception' of the lugs orwing's 7 of the wrench head." The holder 16 is further provided with an annular flange 1'7. In-use, the ribs or wings 7 of the wrench head 6 are .en-

w1th1n the recesses in the outer gaged flanged endof the'holder 16, and one end of the centering element 13 is engaged within the polygonal bore of the washer nut 18 .and the .flange 14: thereof is seated within the annular head 6 .and engaged with the flange 8 thereof. The wrench holder '9 .over the flange 17 of the holder 16 and the head 6 of the wrench as clearly illustrated in Figs. 1 and 2, thus securing the wrench head against lateral removal. from the holder 16 and insuring positive gripping action of the ribs or wings 7 The washer nut 18 may be conveniently removed from within the holder '16 by engaging the laterally projecting head 7 of the wrench handle 5- therein and rotating the wrench in the position upon an object tobe rotated.

2. A Wrench including a handle, an annular head at one end of said handle, a plurality of ribs or Wings projecting axially of said head, a centering element removably positioned in said head, and means for securing said head against lateral movement with relation to an object engaged therewith.

3. A Wrench including a handle, an annular head at one end of said handle, a plurality of Wings or ribs projecting axially of said head, a. centering element removably positioned in said annular head, means for limiting longitudinal mm'ement of said centering element with relation to said head, and means for securing said Wrench head in operative position upon an object.

4. A Wrench including a hai'idle, an, annular head at one end of said handle, a plurality of ribs or Win s projecting axially of said head, a centering element remo'vably positioned in said head, and holder remo'vably engaged. with said head for retaining the latter in engagement With an object including a body plate, an annular flange thereon, and a semi-circular extension on said flange disposed at right angles thereto.

5. A Wrench including a handle, an annular head at one end of said handle, a plurality of axially projecting ribs or Wings on said head, a centering element removably positioned in said head, means for limiting the longitudinal movement of said centering element in one direction With relation to said head, and a holder for retaining said head in operative engagement With an object including a body plate having a radial slot therein, a semi-circular flange on said plate, and an angular semi-circular extension on said flange.
